Objectives
Develop digital speed control for a mechatronic system consisting of a power converter and a brushless DC motor. The system is controlled by a digital system comprising an FPGA and an SOPC processor.
Description
The aim is to encourage students to develop all the functionalities required for speed control of a brushless DC machine. The work is carried out in pairs, each pair having a model for experimental purposes.
Autopilot control is achieved using digital control logic implementing pulse width modulation developed in VHDL language and position sensors.
A speed sensor is then designed, again in VHDL, to enable the measurements required for speed control.
The students then design the entire speed control algorithm, from simulation to implementation on a processor using the C language.
Pre-requisites
- Concept of autopilot control of electrical machines
- Control of a pulse width modulation energy converter
- Sizing of a continuous regulator and its digital equivalent
